This research was intended to test the sorption capacity and inactivation of a glass-fiber substrate coated with iron oxide for the removal of Bacteriophage MS2 and Rotavirus from water. Zeta potentials were determined for Bacteriophage MS2 and Rotavirus at different pH and ionic strength. Batch tests have shown a high removal capacity of MS2. The kinetic process of attachment of MS2 to iron oxide has also proved to be fast. The influence of Ionic strength, initial concentration of viruses in solution, pH and competition with NOM on the viability of viruses and kinetics of iron oxide were the variables considered for these experiments. Column tests have shown a high adsorption capacity of 5.3E10 pfu/g iron oxide at a level of 4 log removal and 6.2E10 pfu/g of MS2 at a level of 2 log removal with an initial concentration of 1E8 pfu/ml of MS2.
